It could be both inside and outside the house, depending on if the contractor fulfiled the "order" correctly. BY RIGHT they were supposed to fuse BOTH within the house. but sometimes they just fuse only port 1. Thus within house port 2 might not be fused. THis one is the thing you got to confirm when they install your TP.
On the other hand, at your riser 2nd port is always not fused. And no, 1 fibre cable has 2 or more strands. so no need to add new fibre optic cables(the black colored one laid in trunking)
Lucky for me and friends' whom I helped supervise installation when they were deploying NGNBN. I made sure they fused both ports.
